BOSS has completely remodeled all of the COSM amps in the GT-100. Reaching far beyond conventional vintage amp modeling, the GT-100 includes a host of all-new amps that deliver amazingly transparent clean tones to ultra-high gain modern sounds and everything in between.

At the core of the GT-100 is BOSS’ new proprietary DSP chip, a blazing-fast processor that provides unparalleled muscle for COSM amps and effects. Thanks to this powerful new chip, the GT-100’s COSM amps sound better than ever before, with a dynamic touch and response that truly captures the feel and expressiveness of the world’s finest tube-based amplifiers.

The GT-100 is also a powerful multi-effects processor packed with a huge array of effects, including overdrives, distortions, delays, pitch shifters, modulation, reverb, and many more. The newly developed ACCEL pedal lets players creative explosive effects in live performance by adjusting multiple effects parameters in real time with one simple foot press.

The GT-100’s user interface has been completely redesigned as well, offering easy, intuitive operation that greatly improves on previous designs. Dual displays make navigation simple while programming tones, with intuitive parameter adjustment via easy-to-grab knobs. The GT-100 also includes the acclaimed EZ TONE, which gives everyone from beginners to pros the ability to dial up world-class tones with just a few tweaks. AMP CUSTOMIZE and OD/DS CUSTOMIZE functions, which enable to create original amps and OD/DS, are newly added to EZ TONE.

Housed in a road-tested, all-metal GT chassis with a sleek black finish, the GT-100 is ready for action on stage and in the studio. Eight onboard foot switches provide control over patch selection, as well as immediate access to the built-in Phrase Looper and ACCEL functions. The integrated heavy-duty expression pedal offers foot control over volume, wah, pitch effects, and more. Additionally, the new quick-access Manual mode instantly transforms the GT-100 from a patch-based multi-effects unit to a pedalboard full of stomps with individual on/off control.
